SELF-THREADING LOOM-SHUTTLE.

SPECIFICATION forming part of LettersPatent No. 72e,se4,uated May 19,1903. Application filed June 6,1902. Serial No. 110,514. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE FAIR, of Salem in the county of Essex andState of Massachusetts, have invented certain new and useful,

Improvements in Self-Threading Loom-Shuttles, of which the following isa specification.

This invention relates toloom-shu ttles, pariicularly of that typecoinmonlyknown as self-threading or hand-threading shut-,-

tles. I 1

A very common way of threading loomshuttles is for the operative to dropor place the thread across or near to the inner end of the threading-eyeand then by placing the month to the outer end of the threading-eye andsucking or inhaling the air through said eye to d raw the thread throughthe eye. This.

cut the threads.

The object of this invention is to provide an attachment for shuttleshaving the usual de livering-eyes and having continuous walls' thatis,walls having no slits, and therefore retaining their originalstrength with an attachment by means of which the thread fromthe cop orspindle may be positively pushed through the eye, thus avoiding thenecessity of inhaling or sucking through said eye.

To these ends the invention consists in the construction and combinationof parts substantially as hereinafter described and claimed.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a plan View of so much of a shuttle as is necessaryto illustrate the invention, said shuttle having the invention in one ofits embodiments attached thereto. Fig. 2 represents a section on line-22 of Fig; 1 looking toward the left. Fig. 3 represents a-section on line3 3 of Fig. 1 looking towardthe left. Fig. 4 represents a sectionon line44. of Fig. 1 looking toward the right. Fig. 5 represents a sectionsimilar to Fig. 4 with the parts in'a' different position. Fig. 6represents a section on line 6 6 of Fig. 1 looking toward the right-with the parts in" the same position in which they are shown in Fig. 5.Fig. 7 represents a section on line 7 '7 of Fig. 6. Fig. 8 represents asection on line 8 8 of Fig. l.

The same reference characters indicate the same parts in all thefigures. V

The body of the shuttle is represented at a and is formed'with the usualcavity 1), one

a suitable cavity, preferablyrectangular in' form, to receive the casingpresently described. This cavity for the casing is formed opposite thethread-delivery eye e, as clearly indicated in Fig. '7.

' The casing for the thread-ejecting mechanism is preferably formed of aflattened tube having 'its open ends abutting against the side walls-ofthe'shuttle and having its rounded bottomresting upon the bottom of thecavity formed therefor in the shuttle and having its upper rounded edgeat or a trifle below the plane of the upper edge of'the side wallsofth'e shuttle, as shown in Fig. 8.

The front Wall of this flattened tube or casing is indicated at f andthe rear wall at f. The

' lower rounded portion of the casing is formed with an opening fthrough which the 9perating-disk, presently described, projects. Theupper edge of the casing is formed with a thread receiving slot 9, whichextends through both walls of the casing and is preferably formed at anangle, substantially as shown in the drawings. One end of this slot--the end which is formed in the front wal1fextends downward to a pointapproximately in alinement with the end of the spindle c to receive andguide the thread after the shuttle has been prepared for use. This guideend of the slot is represented at g in Figs. 2 and 6.

A portion of the front wallf of the casing is out out and bent to form asubstantially horizontal shelf or ledge h, and the rear wall f is formedwith a horizontal slot t'. The casing is secured in its cavity by asuitable means, preferably a screw 70, extending through both walls ofthe casing and into the body of the shuttle, as clearly shown in Fig. 8.Mounted to oscillate within the casing, preferably on the screw It, is adisk Z, having its lower edge extending through the openingf of thecasing and having an arm provided with a slot m. A spring at is coiledabout the stud or screw 7t and has one end secured to said disk and theother end to a suitable pin projecting within the casing. This spring isso coiled as to have a normal tendency to hold said disk and its slottedarm in the position shown in Figs. 2, 3, and 4c.

The thread carrier or ejector is represented at 0 and comprises a fingerhaving a pin 0', which extends through the slot on and enters and isguided by the slot t', formed in the rear wall f of the casing. Theshorter arm of this loosely-pivoted finger is formed with a cam-surface0 and has its outer end preferably notched. to engage the thread, ashere inafter described. This finger is so formed that its outer ornotched end is considerably heavier than its cam-shaped rear end, sothat its outer end will have sufficient weight to cause it to descend ordrop quickly by gravity when moved away from the position shown in Figs.2, 3, and 4. A pin 19 projects inward from one wall of the casing andacts upon the cam-shaped rear end of the finger o to depress said rearend and elevate the outerend and hold it there when the parts are movedfrom the position shown in Fig. 6 toward and to the position shown inFig. 3.

WVhen the shuttle is to be threaded, the thread from the cop is laid inthe thread-receiving slot g and in the notched end of the finger, andthe operative then places one finger against the milled edge of the diskZ and swings the latter in a direction opposed to the tension of thespring a. The first movement releases the short end of the finger fromthe pinp, and the outer notched end then immediately drops until itrests upon the shelf h, whereupon further movement of the disk in thesame direction causes the notched end of the finger to pass along saidshelf and out through the delivery-eye e to the position shown in Fig.6. The thread is then readily grasped and drawn through said eye to thedesired extent. Upon release of the diskl the spring it causes it toswing or oscillate, so as to withdraw the finger 0 and cause thecam-shaped rear end of the latter to engage under the pin 19. Saidcam-shaped end rides under the pinp and is thereby depressed until theouter or notched end of the finger engages the under side of the archformed at the upper meeting-point of the two walls ff, the parts beingso proportioned that they will come to a stop in the position shown inFigs. 2, 3, and 4.

I claim-- 1. Aloom-shuttlehavingadelivery-eye and a casing located inthe body of the shuttle opposite said eye, said casing having athreadreceiving notch in its upper edge, and a movable thread-ejectingfinger mounted in said casing and adapted to take the thread from saidnotch and eject it through the deliveryeye.

2. The combination with a loom-shuttle having a delivery-eye, of acasing contained therein, having front and rear walls and formed with anopening in its lower portion, a swinging member mounted in said casingand projecting through said opening, a spring for moving said swingingmember in one direction, and a finger pivotally connected with saidswinging member and having one end formed to engage the thread.

3. The combination with a loom-shuttle having a delivery-eye, of acasing contained therein, having front and rear walls and formed with anopening in its lower portion, and having a guide-shelf and formed with ahorizontal guide-slot and a thread-receiving notch in its upper edge; adisk having a portion of its edge projecting through said opening in thecasing and having a slotted arm, and a finger having a notched outer endand provided with a pin extending through the slot of the disk-arm andinto the horizontal guide-slot of the casing, a spring being connectedto said disk and a fixed point in the casing to normally hold the fingerin position for receiving a thread in its notch.

4. The combination with a loom-shuttle having a deliveryeye, of a casingcontained therein, having front and rear walls and formed with anopening in its lower portion, and having a guide-shelf and formed with ahorizontal guide-slot and a thread-receiving notch in its upper edge; adisk having a portion of its edge projecting through said opening in thecasing and having a slotted arm, and a finger having a cam-shaped rearend IOO and a notched outer end and provided with GEORGE FAIR.
